In Michigan, non-commercial vehicles are NOT subject to DOT inspection, EVER.
Hence, they CANNOT legally check your fuel to make sure it is non-dyed.
Only COMMERCIAL vehicles here are subject to those checks.
They could ask to check but u can refuse.

Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, TURMOIL, FIASCOS, and HAVOC !
